King Lear - William Shakespeare
"Love's not love when it is mingled with regards that stand aloof from the entire point."
King Lear is old and weary, and has reached the age where it is time to divide his kingdom among his heirs: three daughters named Goneril, Regan, and Cordelia. In a final act of vanity, he tells his daughters that he will determine their inheritance according to how much they profess to love him. Cordelia refuses, and her father disowns her and throws her out of the kingdom. Goneril and Regan inherit the kingdom, but the moment they gain power, they begin to plot against their aging father.
One of the greatest tragedies ever written, King Lear is a powerful, heartbreaking, bleak, and beautiful play.
